|---|---|---|---|---|
Purposedifferent | When assumptions still sit unordered in the room, it weighs uncertainty against leverage. It makes visible which hypotheses should be checked first. | SAAM helps teams judge an architecture’s suitability for selected tasks and changes. It is particularly useful for examining modifiability and comparing architecture alternatives with clear reasoning. | When two variants compete, discussions quickly decide by taste rather than effect. A/B Testing checks behavior under controlled conditions and separates real improvement from chance or expectation effects. | ATAM helps teams weigh architecture decisions when quality goals compete. The team considers business goals, stakeholder expectations, and technical decisions together. The evaluation shows which risks need further investigation. |
Complexitydifferent | Medium | High | High | High |
Timedifferent | 45-60 min | Preparation, scenario analysis, and findings review; effort depends on scope | 1-4 Wochen | Several meetings plus preparation and analysis; total effort depends on scope |
Participantsdifferent | 2-8 | Architecture experts and stakeholders for scenarios and weighting | 1-6 | Evaluation team, architects, and relevant stakeholders |
